Русские несвободные выражения в речи иностранцев: корпусный подход
Errors made in choosing or structuring a set expression are quite common for foreign speakers of Russian even for those with a good mastering of the language. The large amount of these errors is caused by the frequency of set expressions in the language, and is associated with their semantic opacity and with well-known discrepancies between their morphological form and grammatical function. These discrepancies can vary and are depend on the degree of freedom of the expression’s elements (i.e. on the type of the expression).The analysis of errors in set expressions in the Russian Learner Corpus; has demonstrated that the difficulties that the students face can be of different nature and are manifested in various types of expressions. Use of corpus resources such as the Russian National Corpus and Ruskell may help improve students’ proficiency in Russian set expressions. The applicability and effectiveness of these resources varies for set expressions of different types. The paper provides recommendations for choosing efficient corpus recourses, and indicates restrictions of different corpora.
